“The one-two shut-the-hell-up. This is priceless when you’re shopping and your kid won’t shut the hell up: “I’m hungry, I want toys, I need my Insulin…” etc. First smack your kid (the 5 across the eyes technique works). Wait a few seconds for your kid to start crying, then smack your kid again to let him know that you mean business. This usually shuts them up because they see that the amount of crying is proportional to the amount of beatings.“
